- same as #8963 but for initial velocity
- add an example file that demonstrates the influence of the initial velocity
- some fine-tuning for the existing flow example
- complete revision of the constraint.
This is a breaking change, meaning existing constraints won't work.
This is possible because since 2 days ago the whole flow equation did not work at all. Also the existing constraint implementation if buggy and cannot be used to do the Elmer tutorial. Also, the constraint is only used by Elmer and only be the flow equation.
Since nobody complained about the obvious wrong results, we can assume the flow equation was not yet in practical usage (and for FC 0.20 we known that it does not work at all, first with FC 0.20.1).
It is necessary since it must be possible to either input a velocity or an equation. With an equation, a velocity profile can be specified.
- update the flow examples accordingly:
-- simplify them since an initial and and output velocity is not necessary to specify
-- use a formula as input velocity for the non-turbulent example
- it is a long-standing bug that the name of the result mesh object is not unique. For example for a frequency analysis you get for every result the same object "ResultMesh". When now a "ResultMesh" object is deleted because one result mode object should be deleted, all result modes loose their mesh.
To fix this, use a unique name for the mesh object.
- make the connection also working for frequency and buckling analysis by directly creating/updating the pipeline where the CalculiX results are loaded
- for some materials, just opening the material dialog and pressing OK to close it without any change resulted in a transient material
- for other materials this happened by clicking in the material dialog on a value to edit it, but not changing anything and press OK
The fix is to compare the items item by item and also handle the case that only digits of numbers are different
- on creating a new material object, don't pollute the console wit wrong error messages (if no material is yet selected, of course nothing can be found)
- fix that for anew fluid materials the material editor was started with solid materials
- the material editor failed for Fluid materials because this info was not passed to it. Instead always solid materials were loaded.
- also fix warning about too long variable name and remove unnecessary debug code
- it was often criticized that our default solver CCX is not connected to the results pipeline system. One had to connect it manually, the create the different filter etc. but as soon as one changed a constraint and re-run the solver the whole work was gone and one had to recreate the pipeline.
This PR solves this by creating a pipeline and by reloading new results to it on a solver re-run.
The CCX results dialog feature is not touched, since the pipeline is hidden when the dialog is active.
- no longer output an error on mesh from a BooleanFragments. There are cases when this fails, but other cases where one must use a BoopleanFragments compound and this works well, see https://forum.freecad.org/viewtopic.php?t=71070. Therefore a warning is sufficient.
- disable log messages not important for the average users.
- avoid code duplication
- uses the constraint for 2D magnetodynamics to perform e.g. Elmer's tutorial non. 15
- modify the Material manager to get rid of magnetization but keep the vectorial functionality because in future there will be support for e.g. birefringence materials etc.
- as the name implies, it must be possible to set the heat to different bodies
- for this a selection dialog is necessary
- check that heat is not zero
- same fix as commit 7e071623 for flow velocity constraint
- the used selection widget did not highlight the selected faces. This made it very hard to work with when one has an existing document where e.g. 5 faces have a certain velocity and you cannot figure out which ones.
To fix this use another selection widget
- the used selection widget did not highlight the selected faces. This made it very hard to work with when one has an existing document where e.g. 5 faces have a certain voltage and you cannot figure out which ones.
To fix this use another selection widget
- this fixes a mistake from commit ef088674
- it also consistently use the thermal expansion coefficient
- add code comments
now the material task dialog works with all fluid materials without errors or warnings
- since a while ThermalExpansionCoefficient is used, VolumetricThermalExpansionCoefficient is only used for the material task panel
- as already stated in a code comment, the unit of VolumetricThermalExpansionCoefficient is ThermalExpansionCoefficient, therefore we must check for ThermalExpansionCoefficient
- we must also check if ThermalExpansionCoefficient exists
- Adapt the existing fluid material cards to use the ThermalExpansionCoefficient
- they all had the name "figure 1"
- thus make the name unique and this way also enable to have several plots open displaying different result types (for the line filter)
- use for the histogram titles the same as in the CCX dialog and not our internal abbreviations
- in the CCX dialog don't use the term PEEQ but the common wording that also gives the user the info what this is about
